About Converting Pint per Hours to Gallon per Days
Pint per Hours and Gallon per Days both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
gallon per days = pint per hours × 3
This factor comes from each unit's defined relationship to the category's base unit: 1 pint per hours equals 1.314379e-7 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct pint per hours-to-gallon per days factor of 3.
Simple example
1 pt/h × 3 = 3 gal/d
1 pint per hours = 3 gallon per days.
Real-world example
60 pt/h × 3 = 180 gal/d
60 pint per hours = 180 gallon per days.

Frequently asked questions
How many gallon per days are in 1 pint per hours?
1 pint per hours equals 3 gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert pint per hours to gallon per days?
Multiply the pint per hours value by 3. The converter above does this instantly to whatever precision you set.
How do I convert gallon per days back to pint per hours?
Use the reverse factor: 1 gallon per days equals 0.3333333333 pint per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a pint per hours?
Pint per Hours (pt/h) is a unit of flow rate.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
Is the pint per hours to gallon per days conversion exact?
Yes. Both pint per hours and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 3 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
